Modern smartphones Honor have powerful multimedia capabilities that often surpass the built-in functions of even advanced TVs. Watching films, photos from the family archive or playing mobile games on the big screen turns an ordinary evening into a real cinema. However, many users encounter difficulties when trying to synchronize their gadget with a TV running on the platform Android TV.
There are several proven methods for organizing communication between devices, each of which has its own advantages and features. The choice of a specific method depends on your smartphone model, firmware version Magic UI or EMUI, as well as the technical characteristics of the TV itself. In this article, we'll take a closer look at all the available connection options, from wireless protocols to physical interfaces.
Whether you just want to show a presentation to colleagues or enjoy 4K video, proper data link setup is key to success. We will look at the nuances of working with Wi-Fi Direct, features of using adapters USB-C to HDMI and specific settings in the developer menu that may be required in difficult cases.
Technical requirements and equipment preparation
Before starting the setup, you must make sure that both devices meet the minimum technical requirements for the correct operation of multimedia protocols. Your smartphone Honor must support a video signal transmission standard, be it software Miracast or hardware output via MHL i Slimport. Most modern models of the Honor Magic and Honor View series are equipped with full support for video output through the port. USB Type-C.
A TV with an operating system Android TV must have an active network connection. If you plan to use wireless streaming, it is critical that both devices are on the same local network. This means connecting to the same Wi-Fi router on a frequency of 2.4 GHz or 5 GHz. Different frequencies on the same router are usually not an obstacle, but using a guest network or client isolation can block device detection.
Check that the software on both gadgets is up to date. Outdated drivers Wi-Fi module or old versions of system services Google Cast can lead to an unstable connection or a complete lack of signal. It is recommended to go into the settings and check for updates before starting the pairing procedure.
⚠️ Attention: Some budget Honor smartphone models may have a USB-C port, which only supports charging and data transfer, but not video signal. In this case, connecting via an HDMI adapter cable will not work, and you will have to use only wireless methods.
☑️ Checking readiness for connection
Wireless broadcast through the built-in function
The easiest and most popular way to display an image from a smartphone on the TV screen is to use the built-in wireless projection function. In shells Magic UI and EMUI this option may be called differently: “Wireless projection”, “Broadcast” or “Multi-screen Interaction”. The technology is based on a protocol Miracastthat allows you to transmit video and audio in high quality without delays typical of some streaming applications.
To activate the function, lower the notification shade on your smartphone Honor and find the corresponding icon. If it is not on the main screen of the Quick Access Toolbar, click on the edit icon (pencil) and drag the desired icon to the active area. After pressing, the phone will begin searching for available devices within the range of your wireless network.
On the TV side Android TV you need to launch the application to receive the signal. Depending on the TV manufacturer, this may be a built-in function, an application, or native support. Modern clean TVs Screen Mirroring, application AirScreen or native support Google Cast. Modern TVs on a clean Android TV often automatically detect broadcast requests and display a pop-up window asking you to connect.
After selecting your TV in the list on your smartphone, the connection process will begin. The phone screen will be completely duplicated on a large display. It is important to understand that with such a connection image resolution adjusts to the TV matrix, which can lead to the appearance of black bars along the edges if the aspect ratio of the devices does not match.
If the broadcast works with a delay or jerks, try switching the router to a less busy channel or bringing your smartphone closer to TV to improve the quality of the Wi-Fi signal.
| Parameter | Wireless projection (Miracast) | Google Cast (Chromecast) |
|---|---|---|
| Transmission type | Full screen duplication | Broadcasting content from the application |
| Signal delay | Minimum (games) | Average (depending on the network) |
| Battery consumption | High | Average |
| Sound | Transmitted synchronously | Transmitted synchronously |
Use of Google Cast technology
An alternative to complete screen duplication is the use of an ecosystem Google Cast. This method is ideal if your goal is to watch videos from specific applications, such as YouTube, Netflix or ivi, rather than showing off your smartphone desktop. In this case, the phone acts as a control panel, and the TV independently downloads and plays content, which significantly saves battery power.
Make sure that services are installed on your Honor . On new models released after the imposition of sanctions, installing services may require additional steps through utilities like Google Play. On new models released after the imposition of sanctions, installing services may require additional actions through utilities like Gspace or Gbox, however, native Cast support may be unstable in them. If the services are installed, open the desired application with video content.
In the application interface, find the broadcast icon - a rectangle with waves in the corner. By clicking on it, you will see a list of available devices Android TV on your network. Select your TV and the video will start playing on the big screen. At this point, you can minimize the application, answer calls or use other phone functions without interrupting viewing.
It is worth noting that some applications block the ability to broadcast protected content through third-party screen mirroring tools due to policy DRM (Digital Rights Management). In such cases, using the native Cast button inside the application is the only legal way to display a high-quality image without black screens instead of video.
Connecting via HDMI cable and adapters
For users for whom connection stability and maximum picture quality without compression are critical, a wired connection is the optimal solution. This method completely eliminates the influence of interference on the air and network delays. You will need a special adapter USB-C to HDMIthat supports the mode DisplayPort Alt Mode.
Connect the adapter to the charging connector of your smartphone Honor, and then connect it to the TV with a regular cable HDMI. The TV must be switched to the appropriate signal source (for example, HDMI 1 or HDMI 2) using the remote control. The smartphone will automatically recognize the external connection and switch the video output. Some models offer a special mode for a wired connection (analogous to Samsung DeX). In this case, an interface similar to a computer desktop will appear on the TV screen, with application windows and a taskbar. This turns the phone-TV combination into a full-fledged workstation for processing documents or web surfing.

This turns the phone-TV combination into a full-fledged workstation for processing documents or surfing the web.
When using a cable, pay attention to the power supply. Active transmission of high-definition video consumes a significant amount of power. It is recommended to use an adapter with an additional port USB-C to connect the charger to prevent the smartphone from discharging during a long session.
⚠️ Attention: When purchasing an adapter, make sure that it supports 4K@60Hz resolution if your TV and phone have such capabilities. Cheap cables often limit the frame rate to 30 Hz, which makes the picture less smooth.
Why is there no signal through the cable?
If the image does not appear when you connect the cable, check whether your particular Honor model supports video output via USB-C. Also try changing the HDMI cable or port on the TV, as some ports may be faulty or configured to a different version of the standard.
Third-party applications to expand capabilities
If standard system tools do not cope with the task or additional functions are required, applications from the store come to the rescue. Google Play. There are many utilities that implement protocols AirPlay, DLNA and improved versions Miracast. One of the most popular solutions is the application AirScreenwhich is installed directly on the TV Android TV.
Once installed and launched AirScreen on the TV, it emulates a receiver compatible with various standards. On a smartphone Honor you can find this device not only through the standard projection function, but also through the “Broadcast” menu in the connection settings. This is especially useful if the phone's native function does not see the TV for some reason.
Another option is to use applications for transferring media files over the network, such as BubbleUPnP or VLC for Android. In this case, you do not duplicate the screen, but send a specific video file or music for playback by the TV. This reduces the load on the smartphone's processor and allows it to be used for other tasks.
For advanced users with rights Root or access to debugging, there are tools like Scrcpythat allow you to control the phone from the TV (if a mouse and keyboard are connected to the TV) with minimal latency. However, setting up such solutions requires connection via ADB and certain technical knowledge.
Third-party applications often help solve the problem of protocol incompatibility between old phone models and new TVs, acting as a universal signal translator.
Solving common connection problems
Despite Although seemingly simple, the connection process may be accompanied by technical failures. One of the common problems is that the TV does not see the phone in the list of available devices. First of all, check whether the “AP Isolation” function is activated on the router, which prohibits devices within the same network from communicating with each other.
Another common situation is the presence of a picture, but no sound. In your smartphone's audio settings Honor make sure that the audio output is set to an external device or Bluetooth headset if the sound goes there. Sometimes simply switching the sound source in the notification shade during an active broadcast helps.
If the image “scatters” into pixels or is constantly buffered, the problem lies in an overloaded channel Wi-Fi. Try disconnecting other devices from the network or switching your router to a channel with less traffic. For wireless 4K video streaming, network stability is a critical factor.
- 📡 Make sure that the router does not have speed limiting enabled for individual devices.
- 🔄 Reboot both devices: this clears the network services cache and resets stuck connections.
- 🔋 Disable the mode energy saving on the phone, as it can limit the operation of the Wi-Fi module.
- ⚙️ Check the date and time on both devices - desynchronization can block secure connections.
⚠️ Attention: Menu interfaces and item names may differ depending on the version of Android and the Magic UI shell. If you do not find the described function, use the search in the phone settings by entering the keyword “Projection” or “Broadcast”.
Frequently asked questions (FAQ)
